eq1dk

Constraints that some params sum to 1. Used Internally. For data with DK.
Functions for constraining lambdas to sum to 1 and to bound params between 0 and 1

Provides tools to adjust estimates of learning for guessing-related
bias in educational and survey research. Implements standard guessing
correction methods and a sophisticated latent class model that leverages
informative pre-post test transitions to account for guessing behavior.
The package helps researchers obtain more accurate estimates of actual
learning when respondents may guess on closed-ended knowledge items.
